Use Unicode data movement mode when sources or targets use 8-bit or multibyte character sets and contain character data. In Unicode mode, the PowerCenter Integration Service recognizes multibyte character sets as defined by supported code pages.
If you configure the PowerCenter Integration Service to validate data code pages, the PowerCenter Integration Service validates source and target code page compatibility when you run a session. If you configure the PowerCenter Integration Service for relaxed data code page validation, the PowerCenter Integration Service lifts source and target compatibility restrictions.
The PowerCenter Integration Service converts data from the source character set to UCS-2 before processing, processes the data, and then converts the UCS-2 data to the target code page character set before loading the data. The PowerCenter Integration Service allots two bytes for each character when moving data through a mapping. It also treats all numerics as U.S. Standard and all dates as binary data.
The PowerCenter Integration Service code page must be a subset of the PowerCenter repository code page.
